Solution (part 1-original): a=8 cm^2, b=3 cm^2, c=15 cm^2
Step by step solution:
The way you find area of a parallelogram is base times height so in A it would be 2x4 so 8 cm^2. You need to add the unit and have it squared to show that it’s representing a 2d space instead of a length
Solution (part 2-enlarged): a=32 cm^2, b=16 cm^2, c=60cm^2
Step by step solution (part 2):
It’s basically the same as before except that you multiply the side lengths by 2 BEFORE multiplying the height and base. So a would be (2x4)x(2x2) or 8x4=32.
Answer:
The numerator factors to
The denomenator factors to
16.8-8.3=8.5
You round the numbers with decimals to their tenths place and then subtract normally.
Answer and Explanation:
A function is said to be increasing, if the derivative of function is f’(x) > 0 on each point. A function is said to be decreasing if f”(x) < 0.
Let y = v (z) be differentiable on the interval (a, b). If two points z1 and z2 belongs to the interval (a, b) such that z1 < z2, then v (z1) ≤ v (z2), the function is increasing in this interval.
Similarly, the function y = v(z) is said to be decreasing, when it is differentiable on the interval (a , b).
Two points z1 and z2 Є (a, b) such that z1 > z2, then v (z1) ≥ v(z2). The function is decreasing on this interval.
The function y = v (z)
The derivative of function Y’ = v’(z) is positive, then the function is increasing.
The function y = v (z)
The derivative of function y’ is negative, then the function is decreasing.
The answer is A
One revolution is equal to the circumference of the tire:
C=2pi r=2(1)(frac{22}{7})=\frac{44}{7}
The car travels at 4,400 ft per minute. To calculate the number of revolutions, divide the speed by the circumference:
4,400div frac{44}{7}=4,400times frac{7}{44}=700
700 revolutions.
